How the OBBBA Equity Tailwind Could Lift Markets

The OBBBA Could Deliver Another Major Boost for Equities in 2026

Most analysts expect stocks to climb again in 2026, thanks to a steady pace of interest-rate cuts, a resilient economy, and growing confidence in a broader AI-driven rally. But Societe Generale’s Manish Kabra, head of U.S. equity strategy, points to an additional—and powerful—tailwind: the One Big Beautiful Bill Act (OBBBA).

In a recent report with SocGen’s global head of equity strategy, Charles de Boissezon, Kabra notes that the OBBBA “authorizes one of the largest spending packages in recent history,” channeling $4.1 trillion through 2034 toward defense, infrastructure, and targeted tax measures. If temporary provisions are made permanent, spending could rise to $5.5 trillion.

This massive stimulus is expected to push annual fiscal deficits above $600 billion after 2025, before easing below $400 billion after 2030. Historically, that’s positive for equities: profit margins tend to rise roughly one year after deficits increase, SocGen notes.

Five OBBBA Themes and the Stocks Poised to Benefit

SocGen outlined five core themes within the OBBBA and built a 30-stock basket of potential winners.

1. Capex Revival

The OBBBA reinstates and expands investment incentives aimed at strengthening domestic production. Lowered investment costs and improved cash flow should encourage companies to upgrade equipment, expand facilities, and accelerate R&D.

Potential beneficiaries:
Caterpillar (CAT), Cummins (CMI), Deere (DE), Eaton (ETN), Nucor (NUE)

2. A Defense Spending Lift

Roughly $150 billion, much of it front-loaded into 2026, will support the U.S. defense industrial base and critical mineral supply chains.

Potential beneficiaries:
General Dynamics (GD), L3Harris (LHX), Northrop Grumman (NOC), Huntington Ingalls (HII)

3. Tax Changes Increasing Disposable Income

Tax adjustments in the OBBBA should boost disposable income—mainly for middle- and high-income households. That supports consumer discretionary sectors like retail, autos, and leisure. Meanwhile, reduced SNAP and Medicaid funding could pressure staples and discount retailers.

Potential beneficiaries:
Ralph Lauren (RL), Tapestry (TPR), Costco (COST)

4. Support for Small Businesses

Targeted tax relief and expanded financing tools are designed to help early-stage investors, improve after-tax earnings for small businesses, and drive loan demand for community banks.

Potential beneficiaries:
KeyCorp (KEY), M&T Bank (MTB), Apollo (APO)

5. Energy Sector Upswing

The OBBBA is a clear positive for oil, gas, and coal producers—especially those operating in Alaska and the Gulf. It’s less favorable for large wind and solar developers that depend on federal land. The plan reinstates onshore and offshore drilling rights.

Potential beneficiaries:
Exxon Mobil (XOM), ConocoPhillips (COP)
